I think I bought Feud for the excessively high price of 1.99... I loved the way your opponent was someone very like you, who was going round doing his own thing, collecting herbs etc somewhere on the map and not necessarily trying to take you on directly until they were strong enough.

The collecting and combining herbs parts of Oblivion totally reminded me of this game.

I remember playing Driller, don't think I ever got very far with it though!
